Correct Hollins, it's on the walk down from Denbigh Castle and has a connection with the Mabinogion in that Blodeuwedd who was transformed into an owl. There is also a sculpture in the wall slightly further up the lane. (See attached pic). The passage below is from Google on the sculptures.
"Joss Smith, from London, has produced an eye catching sculpture placed at the turn in the lane at Temple Bar Gardens which can be seen from the High Street. He has also produced two smaller sculptures that ‘fly’ out of the wall part way up the lane. Joss’s designs are based on the Welsh mythological Mabinogion’s character, Blodeuwedd and the nine flowers of power. One of the flowers is a broom flower."
